Here is a small list of short-term development plans. I hope to get all this done in the next week or so. Once these are done, I will release a new version 0.04.

1. separate the CRC code to its own file
   
2. add optional DC high-pass and LFE low-pass filters
   
3. completely redo the variable bandwidth system
4. add an optional bandwidth low-pass filter
5. overhaul the configuration system
   
6. separate aften frontend, libaften, libfilter, and utils
